Cumulative distributions of hourly median basic transmission loss are presented for 135 beyond-line-of-sight radio paths in the United States. In order to allow for seasonal trends of transmission loss, the year is divided into a summer period, May through October, and a winter period, November through April. The long-term variability of observed hourly medians is compared with predicted variability based on empirical curves by Rice, Longley and Norton.
